Wipe and between element 125 and the second friction element 130, form friction lock, so as to pass between friction element support 110,115
Torque delivery.The not shown axial accordingly manipulation device for providing axial compression power in FIG.
Not only the first friction element 125 and also the second friction element 130 can be loaded with friction on its axial face respectively
Liner 135.Do not have the modification of friction facing 135 equally feasible completely.Friction facing 135 is wear-resistant in an ideal way
, highly can load, long-life and realize setting up as homogeneously as possible and separate friction lock in other words.
Here is advised, the opening characteristic that setting flexible member 140 is used for improving further clutch apparatus 100 is closed in other words
Close characteristic, described flexible member is respectively between the first friction element 125 and the first friction element support 110 or second
It is located at the first friction element support 110 and the second friction in scope between friction element 130 and the second friction element support 115
In power stream between element bracket 115.
Fig. 2 illustrates the axial view of the friction element 125,130 of the example of clutch apparatus 100 of Fig. 1.According to Fig. 1's
Diagram the first friction element 125 has the connecting plate 205 projecting radially outwardly, and described connecting plates are designed to, and are coupled to first
In the corresponding breach of friction element support 110.Described breach extends in friction element support 110 in the axial direction, thus
In the axial direction during extrusion friction group 120, the first friction element 125 can with respect to the first friction element support 110 in the axial direction
